How Arizona Public Service Reduced Contract Generation and Invoicing Time by 90%
Customer Arizona Public Service (APS) supplies power to about 1.4 million customers and is the state’s largest and longest-serving energy provider with nearly 6,000 employees. APS has a diverse and growing generation portfolio of more than 4,000 MW.
Background Each quarter, APS invoices more than 550 counterparties for production-based incentives for wholesale-level, small-scale solar. Associated complex billing processes end up taking several days due to different payout rates, as well as different contract start, end, and incentive dates.
Results APS went from spending an average of 5-8 business days on its quarterly counterparty contract management and invoicing processes to less than one day.
Project Information
APS was using a disjointed, time-consuming spreadsheet-based system to ensure business rules worked correctly with invoiced amounts coming from a separate system.
Meter data and reporting were only available quarterly around the time of invoicing, so the information couldn't be checked ahead of time.
This required an automated bot to access webpages and download invoices, which tied up the computer running the program. If the bot failed, APS staff had to rerun the bot and redownload invoices.
One System for All Contract Functions
APS now uses ContractCore for all of its counterparty contract management and invoicing workflows, replacing a process that utilized multiple systems and spreadsheets.
